Question

Explain how to arrange the following in increasing order of atomic size/radius: Al, C, Si​

Answer 1

C, Si, Al

Step-by-step explanation:

We use periodic trends to help us find the atomic radii. The trend for atomic radii on the Periodic Table of Elements is down and to the left. So whichever elements are furthest to the left and farthest down have the largest atomic radii.
